GardenSmart Guide to Non-Invasive Plants



The GardenSmart booklet has information about the many choices of plants that work for gardens while protecting watershed health. GardenSmart also highlights plants you should avoid because they are invasive, and has information about non-invasive alternatives (both natives and non-native ornamentals) that you can safely plant instead. Please use this booklet as a guide to help you make informed choices for your garden, water garden or landscape.
